Heat shield for a motorcycle

ABSTRACT

A heat sheild to be connected to a motorcycle frame and extending over the exhaust of the motor vehicle so that the motorcycle can accommodate a passenger riding behind the driver without being burned by the exhaust pipe of the motorcycle, the heat shield comprising a surface to overlay the exhaust in spaced relation and including means to connect the same to the motorcycle.

3 Claims, 4 Drawing Figures 2a zz HEAT SHIELD FOR A MOTORCYCLE FIELD OFTHE INVENTION This invention relates to motorcycles and moreparticularly to a heat shield for connecting to the motorcycle tooverlay the exhaust of the motor vehicle in spaced relation so that thevehicle can accommodate a passenger riding behind the driver.

BACKGROUND OF THE INVENTION As is perhaps well known motocycles do nothave much room for passengers. Ordinarily a passenger rides behind thedriver. There is a danger of being burned when one sits on the rearportion of the drivers seat, since the exhaust of the motorcycle extendsrearwardly face temperature. A person seated on the rearmost portion ofthe seat 22 of the motorcycle is thus provided below the seat and theinside surface of the thigh of a passenger can easily be burned if itcomes in contact with the exhaust. This invention provides a heat shieldwhich companionately cooperates with the muffler housing of a motorcycleand in effect extends it beneath the rear portion of the drivers seat,the heat shield comprising a roof and sidewall which are spaced from thehot surface of the exhaust so that a passenger touching the heat shieldwith his leg will not be burned.

OBJECTS OF THE INVENTION It is the general object of this invention toprovide a heat shield for the longitudinally extending rearmost portionof the exhaust of a motorcycle which shield includes an abutment surfaceto overlay a surface of the motorcycle inboard of the exhaust whichincludes mounting means to connect to the motorcycle and a roof and sidewall extending in spaced relation from the exhaust in an outboarddirection and downwardly relative to the exhaust, so that a passengerriding on the rear part of a motor vehicle seat will not be burned.

In accordance with these and other objects which will become apparenthereinafter, the instant invention will now be described with referenceto the accompanying drawings.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial view of the rearmostportion of a motorcycle;

FIG. 2 is an outboard elevation view of the heat shield of the instantinvention;

FIG. 3 is an inboard elevation view of the heat shield of the instantinvention; and

FIG. 4 is a perspective view of the heat shield showing its constructionand configuration.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings whereinlike reference characters designate like or corresponding partsthroughout the several views, the numeral 12 generally designates therear portion of a motorcycle while the numeral 14 designates the heatshield. As is apparent from F IG. 1, the heat shield extendslongitudinally rearwardly from the rearmost portion 16 of the mufflerprotectively overlaying in spaced relation therefrom the exhaust 18 ofthe vehicle, which is in use has a high surwith protection from the hotexhaust, so that he will not be burned.

The heat shield is generally best seen in FIG. 4. It is seen to comprisean abutment surface 26 to overlay the conventional surface of the frameof the motorcycle inboard of the heat shield, the abutment surfaceincluding mounting means 28, which may be an upwardly directed slot 30which is enlarged in a longitudinal direction, as at 32, to slide overthe head of a mounting screw which is thentightened The heat shieldincludes a roof 34 of arcuate configuration which extends upwardly andoutwardly from the abutment surface in spaced relation above the exhaustof the motorcycle and thence downwardly in a skirt 36 which overlays theoutboard side of the exhaust in spaced relation. The leading or forwardedge 38 of the heat shield is configured to companionately mate with thesurface of the conventional muffler on the motorcycle involved and,preferably includes a downwardly extending edge 40 which, at its upperend traces a fair curve 42 so as to match the arcuate surface of themuffler housing at about the juncture of the exhaust portion and mufflerof the motorcycle. The rearmost portion of the shield defines a faircurve indicated by the numeral 44 which is decorative generally andcurved so as to provide a pleasing and smooth appearance while thedistance between the edges 38 and 44, that is between the leading edgeand the trailing edge, is sufficient to provide an extension whichprotects against burns from the hot exhaust. The shield is extremelycolored to harmonize with the color scheme of the motorcycle.

What is claimed is:

l. A heat shield for the longitudinally extending rearmost portion ofthe exhaust of a motorcycle which has a rear part of the operators seatabove the exhaust portion, said shield comprising: an abutment surfaceto overlaya surface of the motor vehicle inboard of the exhaust portion,the abutment surface including mounting means to connect to the surface,a roof of arcuate configuration extending upwardly on the inboard sideof the exhaust portion in spaced relation therefrom, outwardly above theexhaust portion and downwardly in spaced relation of the exhaust portionand including a skirt which extends generally vertically downwardly inspaced relation on the outboard side of the exhaust of the motorcycle.

2. The heat shield as set forth in claim 1 wherein the mounting meanscomprise a vertical slot having a longitudinally extending portion atits upper end to accommodate and nest over a headed screw on the frameof the surface of the motorcycle.

3. The device as set forth in claim 1 wherein the roof and skirt have aleading and a trailing edge and the leading edge is curved to mate withthe rearmost portion of the manifold of a motorcycle to provide agenerally continuous surface, the heat shield, when mounted to amotorcycle comprising an extension of the muffler housing surface of themotorcycle. i 4 l 4 4

1. A heat shield for the longitudinally extending rearmost portion ofthe exhaust of a motorcycle which has a rear part of the operator''sseat above the exhaust portion, said shield comprising: an abutmentsurface to overlay a surface of the motor vehicle inboard of the exhaustportion, the abutment surface including mounting means to connect to thesurface, a roof of arcuate configuration extending upwardly on theinboard side of the exhaust portion in spaced relation therefrom,outwardly above the exhaust portion and downwardly in spaced relation ofthe exhaust portion and including a skirt which extends generallyvertically downwardly in spaced relation on the outboard side of theexhaust of the motorcycle.
 2. The heat shield as set forth in claim 1wherein the mounting means comprise a vertical slot having alongitudinally extending portion at its upper end to accommodate andnest over a headed screw on the frame of the surface of the motorcycle.3. The device as set forth in claim 1 wherein the roof and skirt have aleading and a trailing edge and the leading edge is curved to mate withthe rearmost portion of the manifold of a motorcycle to provide agenerally continuous surface, the heat shield, when mounted to amotorcycle comprising an extension of the muffler housing surface of themotorcycle.
